I am going through trying to disable unneeded services and whatnot on my linux box and I was wondering something. This answer to this question may be very obvious...but...I have a cable internet connection and I do not need PPP right? I am using update-rc.d -f <daemon name> remove to tidy up the install and I wanted to make sure before I inserted ppp in place of <daemon name> and then ended up needing it.
